Note that people who opt to sit on Exit Rows on the 747-400s, in economy class will have to endure one thing. The entertainment console juts inward from the armrest so your 'hip space' is limited by about an inch. The seat can be snug if you know what I mean. I have seen fellow passengers really squeezed into the seats.... I felt sorry for them. But the plus side is that you have loads of leg room.
